Selling my KW CS coilovers, which have served me well. They have 15k miles and roughly 20-25 track days on them, and adjustments in damping still make a big difference (meaning they don't need rebuilding anytime soon). They make a tremendous difference from stock, particularly powering out of corners. I always ran high 2's camber front and they rocked. There is nothing wrong with them at all, I just no longer track this car so I don't feel the need to keep expensive coilovers on it. They are already packed up and ready to ship at buyer expense (31x19x9 and 61.5 pounds from 37660). There are a few scrapes here and there to be expected with used suspension parts, but mechanically they are rock solid.

Feel free to message me on here with questions. These are the best coilovers on the market for the price IMO. You can get better, like MCS, but not for anywhere near KW CS price.

thank you sir...really looking forward to getting these on the track and testing the difference.....

hey real quick off hand when do you think i should think about rebuilding these?

On my z4m I had to rebuild the rear passenger after aprx. 12K miles of mixed use. The reservoir seal dried out and shrunk causing a noticeable leak on the garage floor. The other three corners still felt/looked as good as new.

Yeah, it really depends on the specific shock/strut and use. The old rule of thumb from racing is to rebuild when adjustments in reb/comp stop making much difference or when they visibly leak, neither of which has occurred here, but shocks can go one season or many many seasons depending on driver, track, and the particular shock at issue. My formula mazda could go several seasons w/o a rebuild at the level I was driving it and the penske DA's it had on it, but some others with similar shock setups could last 1-2 seasons.
